This person was originally a subordinate of Yuan Shao, a hegemon of the Three Kingdoms, and only later did he turn to Cao Cao's command, laying the foundation for Cao Cao's unification of the north, but unfortunately, such a rough wizard died of illness at the time of Cao Cao's crusade against Karasuma, at the age of 38; and later generations all praised his strategic deeds, and Cao Cao personally praised him for knowing people; and modern times have rarely stopped talking about him compared with Zhuge Liang.
This person was Guo Jia; Guo Jia assisted Cao Cao for eleven years, and during these ten years he advised Cao Cao and traveled in the battlefield without stopping; Cao Cao's conquest of the world was blocked everywhere, and the heroic Cao Cao was not satisfied with the existing territorial area of the Wei state; Cao Cao was not a contented person, and Cao Cao, who liked to gamble, almost never rested, but Guo Jia's death overshadowed Cao Cao for a long time.
Guo Jia's death is not the only reason for the obstruction of the unification of the world, but it can also be regarded as one of the main reasons. At that time, the generals were exhausted and the horses were short of food, but Guo Jia advocated attacking, and was sure to usher in a great victory, and finally Lü Bu was captured. However, in the next few battles, Guo Jia thought of Cao Cao several times, and whenever Cao Cao was difficult to decide on something, but had a slight eyebrow, Guo Jia would always take the initiative to put forward his own opinions for Cao Cao, and even help Cao Cao make up his mind, and even said that Guo Jia laid the foundation for Cao Cao's fierce and fierce character.
And if Guo Jiazai had been defeated in the Battle of Chibi and the State of Wei, would he have been able to predict the strategy of the Shu and Wu kingdoms in advance? Or if Guo Jia was still alive, would he be able to make Cao Cao turn the situation around and turn defeat into victory?
